L1 emulator for LLP displaced jet trigger (L1 6:1 LUT, L2 jet algo), L1TNtuples addition of jet hwQual #36919

gk199 · 2022-02-09T15:31:43Z

PR description:

This PR implements the L1 emulator of the LLP displaced jet trigger algorithm. Calo L1 takes the 6 fine grain bits from the HCAL uHTR (PRs #34600 and #35599) and uses a 6:1 LUT to set a single bit of tower hwQual based on the logical OR of the timing and depth information. The Calo L2 jet algorithm flags a jet as delayed if there are >= 2 flagged towers within the 9x9 jet region. This is saved in the LSB of jet.hwQual, 1 if jet is flagged as containing an LLP, 0 otherwise. L1 and L2 firmware updates have been completed.

The uGT emulator follows, and is implemented in recent PR #36868. L1 Menu Tools is in the process of being updated to include the displaced jet bit, in PR #74.

The L1 seed JIRA ticket, including slides detailing the testing of the L1 emulator and links to relevant presentations, is here. Slides 2-10 focus on the L1 emulator implementation and validation tests.

The emulator implementation has been presented at L1 Trigger CMS Week and to the HCAL Trigger group.

Additionally, the L1TNtuples are updated to store the jet hwQual information (in L1AnalysisL1Upgrade.cc and L1AnalysisL1UpgradeDataFormat.h). Tested by myself and @elfontan.

A single comment in HcalFinegrainBit.cc is updated to reflect the correct assignment of the 6 fine grain bits from the uHTR.

PR validation:

Passed runTheMatrix.py tests. Tested in CMSSW_12_3_X_2022-02-08-1100.

L1T DQM histogram comparison comments:

Changes are seen in the jet QUAL bit plot (CenJetsQual), and are expected. The Stage2Layer2JetAlgorithmFirmwareImp1.cc sets the least significant bit of jet hwQual (to 1) if the jet is found to be delayed based on the HCAL feature bits. This bit is set infrequently, as seen in the central jet quality histogram.
In the DQM histograms, I also see the HCAL Feature Bit occupancy histograms at Layer 1. This is also expected since the feature bit is now being set based a 6:1 LUT from the 6 fine grain bits from the HCAL uHTR (update to Layer-1 logic, as previously the feature bit just relied on the first uHTR fine grain bit).

I added some suggestions above in CaloLayer1Packer.cc, please let me know if there are any other thoughts to resolve this (or input from someone from L1, @cecilecaillol?). Is there a way to test the ASAN build locally, with a command to run to reproduce the error?

Is there a way to test the ASAN build locally, with a command to run to reproduce the error?

Yes, you can check the latest ASAN build from the IB dashboard and run a failing workflow there, e.g.

cmsrel CMSSW_12_3_ASAN_X_2022-02-28-1100
cd CMSSW_12_3_ASAN_X_2022-02-28-1100/src

@gk199 Could you check if your suggested fixes above remove the errors?

I tested my suggested fix, and still have the heap-buffer-overflow issue. I also tested a number of other modifications, such as doing the 6:1 logic in CaloLayer1Packer.cc prior to passing through setFB instead of doing the 6:1 logic in UCTCTP7RawData.h.

Any other suggestions or guidance will be much appreciated as I work to resolve this.

Many thanks @dan131riley for the fix and the explanation! I confirm this resolves the step2 heap-buffer-overflow from CaloLayer1Packer::makeHCalTPGs when running runTheMatrix.py -l 39834.0 in CMSSW_12_4_ASAN_X_2022-03-14-1100.

However, I see an error in step3, which seems unrelated to any code in this PR, as it is part of HGVHistoProducerAlgo.

As this is an unrelated file to this L1 emulator PR, may I now open a new PR to fix the heap-buffer-overflow with the changes in CaloLayer1Packer::makeHCalTPGs?

@gk199 please make a new PR with the step2 fix. The fix is clearly correct and needed, the step3 error can be dealt with separately.
